ClearCase® Version Tree

The ClearCase® Version Tree view displays a graphical view of the version history for a ClearCase® element. To open the ClearCase® Version Tree, right-click a resource in a ClearCase® view and then select Show Version Tree on the context menu.

The ClearCase® Version Tree view opens and displays a partial tree for the resource, which includes only the contributing versions for the version currently selected by your ClearCase® view. For example, only the versions and branches that are directly connected to the view-selected version are shown. Click the icon to fetch the missing versions and complete the version tree.

In the ClearCase® Version Tree view, each version of a resource is displayed as a node on the tree, and the version currently selected by your view is marked with the icon. You can use the ClearCase® Version Tree view to perform ClearCase® operations on resources by right-clicking on a version node, a branch, or a merge arrow and then selecting a ClearCase® operation.

Note: You can also navigate the ClearCase® Version Tree and perform operations on resources by using the keyboard. For more information, see ClearCase Version Tree shortcut keys.

Information about versions in the ClearCase® Version Tree

In addition to displaying the versions of a ClearCase® resource, the ClearCase® Version Tree view also displays detailed information about a version, including any metadata attached to the version and the current state of the version (for example, checked-out).

Checked-out versions are marked with a green check mark.

Metadata attached to a version is displayed to the right of the node. If the metadata display is truncated, you can hover over the text to open a larger metadata display box.
